CPU Mining Advice

[Flying Hellfish]

I just picked up a new workstation yesterday.  I use it for work 9-5 M-F and it was configured for my work requirements.  Based on the specs of the machine it may make a decent CPU coin miner in the off times (overnight and weekends).

Dual Intel Xeon E5-2560 8 core CPU's
128 Gig Ram (64 per CPU)
Asus Mobo
1300 watt platinum Antec PSU
2 x R9 280X GPU (on order, eta is early Jan, using a single 7750 till new cards arrive.
Win7

When the 280X's arrive I will put them on LTC when the machine is not in use at work, but what about CPU mining?  Should I be looking at mining a CPU coin like Prime/XPM or Quark?

Note: If it matters to anyone I am not stealing computing power or electricity as I own the company, just looking to see if it makes any sense to mine a CPU coin in the off hours to help offset the cost of the new workstation.

It's certainly worth a shot.  You should be able to get a decent return, especially if you catch the right coin at the right time.  XPM and PTS are both getting difficult now with 10 Primes being required for any real return.  Frozen is an option but they aren't listed on an exchange yet, so not sure if that's a route you want to go.
